15 Claims. (Cl. 123-52) This invention relates to fuel supply means for tially separated from each other in their bore by internal combustion engines and the like which annular bafiles in having holes l2 therethrough employ gasoline, kerosene, or other liquid fuels, which permit the flow of mixture between the and particularly to the manifolds therefor. The header sections as hereinafter described. These 5 invention has for its principal object, the provibaffles are an important factor in the operation 5 sion of means which assist in the formation of of my manifold in that they effectively minimize the fuel-air mixture and deliver said mixture to the pulsations or surges which frequently interthe cylinders in like quantity, quality, and in fere withproper multi-cylinder engine operation proper condition for efiicient and trouble free and performance, particularly at some one speed engine performance, particularly with kerosene range. At the same time, the bafiles sufficiently 10 or even heavier hydrocarbon fuels. Further obpermit the flow of mixture therethrough (in rejects of the invention are to provide an improved sponse to the suctions of cylinders separated intake manifold suitable for use with two or thereby) so as to cause a more uniform flow more carburetors as is common for some engines, through each of the carburetors and thus avoid for example marine engines, and to provide an a complete or troublesome stoppage of the flow 15 improved exhaust-heated intake manifold for inthrough any one of said carburetors, which would ternal combustion engines with or without a occur but for the passage inthe baflies. Thus my water-cooled jacket for such exhaust-heated manifold, by reason of the baffles, eliminates manifolds. trouble due to manifold surging and provides the Referring to the drawing, which illustrates a desired constant flow through the carburetor sys- 20 preferred embodiment of my invention:-- tem. Actual engine operation has shown that the Fig. l is a view showing my improved manifold entire range of engine speeds may be covered as applied to a six cylinder engine of marine type, without troublesome manifold surging or carthe manifold itself, being shown principally in buretor stoppage. Both of these features therehorizontal cross section with certain minor porfore, serve to provide more uniform g ne opera- 25 tions thereof, shown in plan; tion and to secure more uniform distribution of Fig. 2 is a vertical cross sectional view of the the fuel-air mixture to the respect v cylinderscomplete manifold taken on the line 22 of The specific co s as Shown is that p- Fig. 1; plied to a heavy duty six cylinder marine engine Fig. 3 is a vertical cross sectional view taken in which it is desired to burn kerosene and other 30 on line 3 -3 of Fig. 1; and. hydrocarbon fuels somewhat heavier than ordi- Fig.4 is a perspective view showing a connecting y present day gasoline Such p p bushing as employed in the manifold of Figs, 1 3 the intake manifold as described, is provided with Referring to the drawing in which like nua novel exhaust-heated portion consisting of an merals represent like parts, exhaust passage I4 surrounded by a cylindrical 5 The intake manifold, in this embodiment for jacket l6 and, since the manifold is designed for a six cylinder marine engine, consists of three ma the exhaust jacket is q pp With riser or inlet pipes, generally designated at 2, a surroundin cyl ndri al wat riac t 8,wh which lead from the three carburetor portions 3 y e exterior of the manifeld is nta e by (th complete arburetors not being shown) d circulating water at the desired temperature. The 40 connect respe tively with the header portions 4. exhaust gases are conducte the Space Each of said header portions connects with outthrough p p al y desig a d at 20 adin let branches, generally designated at 6, leading from the Siamesed exhaust valves 2| of the engine, from said header portions to the intake valves the exhaust es being brou into tac 1 of the various cylinders. The headers 4 are with deflectors 22 at each T of the headers l. 45 shown connected with each other as at 8\ so that The size or mass of the deflectors is determined they in effect become 'a single long header with by the degree to which it is desirable or necessary the opposite ends thereof closed by plugs 9. The to heat the fuel-air mixture. When the larger connecting telescopic joints 8 are fitted to allow heat transfer is required, dependent upon the fuel for expansion and contraction due to differences and the load and speed conditions, the projection 50 in temperature, and to permit slight relative of the deflectors may be reduced in size or altomovement of the headers 4, though the sliding gether omitted so that the exhaust gases impinge joints are not essential and the entire length of squarely upon the outside of the header 4, the header may be formed integral. The headers as curved exterior plane thereof being more nearly shown, though connected as described, are partransverse to the exhaust gas flow than would the sides of the deflectors. As will be seen from the drawing, the exhaust-gases are free to circulate Within the jacket I4 and pass therefrom through the outlets 24 into the usual exhaust line consequently, are carried left and right in accordance with the induction cycle of the engine. In order to care for the differences in temperature in the manifold, as just described, I preferably cast the exhaust and water jackets l6 and I 8 respectively, out of an alloy of aluminum or other leading therefrom and separate inlet conduits suitable metal having a relatively high heat conductivity. The temperature of these jackets is of course always less than that of boiling water while the temperature of the header portion of the manifold of the type shown may be considerably higher, but, since the header portion of the manifold is made from iron or other material having a co eflicient of expansion (due to temperature) materially less than the surrounding aluminum jacket, the temperature difference does not result in destructive expansion.
The header portions 4 of the manifold shown are held in place by bushings 26 (see Fig. 4) flanged at one end 26a and threaded at the other 261), so that the bushings when threaded into the correspondingly threaded portions of the header, serve to hold the same in position. It will be seen from the drawing that each riser portion 2 includes one of said bushings as well as each intake branch 6 so as to complete the induction system.
Though the manifold as shown is for a six cylinder engine, the invention is equally useful for a four'or eight cylinder engine having two or four carburetors respectively. The spacing and the relations of the inlet conduits and cylinders are, in such cases, essentially the same for each,
two cylinder unit or pair. It is also contemplated that the manifold of this invention may be employed with down-draft carburetors in which case the inlet header 4.
